Abstract

Aiming at the similarity problem of underwater non-contact explosion scale model test, this paper adopts similarity theory to discuss the influence of single value physical quantity on the impact factor of underwater explosion under the premise of satisfying the single value condition. When the damage mode of the ship structure is limited to the large plastic deformation range, this paper derives a new type of impact factor under the condition of the plane wave effect of the underwater non-contact explosion shock wave from the angle of similar single value. This paper takes the typical flat plate, stiffened plate frame and midship section structure of a certain type of ship as the research object, adopts the method of combining numerical simulation and experiment, under different scale ratio conditions, from the deformation deflection and deformation speed of the target structure and stress changes to evaluate the effectiveness of the new impact factor. The results show that the new impact factor has a greater improvement in the accuracy of the model test to the prototype conversion than the traditional impact factor.
